This invention relates to wheeled conveyers, `having been devised with special reference to embodiment in a'trolley conveyer adapted for mechanical uses, though not lim-y .ited in its useful applications to suchparticular type of apparatus.

The accompanying'l drawing illustrating the invention is a central 'transverse sectional viewpthrough the trolley portion of a suso pended conveyer, parts being brokenv away.

i In this drawing 2 indicates a load carrier which in the particular instance is 'a hanger of a trolley conveyerl- The lower portion of this hanger is not represented.' It may bel a hook or other means for carrying a load. It

is supported centrally by a shaft' 3 on which are supported wheels 4, 4', adapted to run. upon tracks 5'.v Ivl refer thatthese wheels should be mounted irectly upon sleeves 6 secured fastto the shaft 3 near its ends and ex.-

tending through the hubs of the wheels, the

bushings being a little longer than the Wheel hubs so that they project beyond the ends thereof andmay take theoutward end thrusts of the inner race elements of the roller bearings 9, which are interposed between the shaft. y and a housing or casing 7 located betweenthe Y Wheels. Nuts 15 secured to the shaft at its ends bear against the outer ends of the bushings. 'The nutsare preferably provided with some sort of locking' means to prevent their turnin upon the shaft after being adjusted to the esired position. I

The load carrier 2 is hung from the housing or casing 7,. the latterl extending throughI an eye 8 formed in the up `er end of the carrier.' 4, 1s free upon the sleeve provided with an oil cup "6 and is preferably 1e other 14 or other means for lubrication.

o wheel, 4, is secured fast to the shaftl 3, so as tov turn therewith and with the sleeve 6 on which itis directly mounted, by means of a set belt 10 thatpasses through a slot 16 in the bushing. The? slot permitsthe ',wheelto be adjusted endwise upon the shaft and "sleeve to the desired position, relative to the adjacent antifriction bearin By theiconstruction an arrangement of the parts that have been referred to, as described,

that is with the wheels supported at the ends of the shaft, the load carrier supportedby a Acasin or housing situated between the wheels andt e antifriction bearin s-located between the shaft andthe housing, t eb'endingfstresses upon the shaft are minimized sov that the latter may be of materially smaller size for a 9-before being set.

carrier intended to transporta loadv of a given -weight than is practicable in -a wheel trolle constructed with the antifriction bearings d1- rectly between .the wheels and the-shaft and the load carrier hung dire'ctl'y upon the ,shaft between the wheels.. The nds of the hous-A ings 7 arepreferably` overhung or covered by the flange and inner tread portions ,of the wheels as clearly represented in the drawing.

The antifrietion bearings may be of any `l`usual or desired construction, within widelimits, and hence need not be herein described in great detail.` Suiice it to-say that the drawl l l ings represent roller bearings with the usual inner races 11 secured to the shaft and'upon which the rollers of the beaiin s run, and the outery races 12 thatlare secure y mounted in the housing 7 Washers 13 arerepresented as arranged. at the outer Aen `of the casing, fand between the roller bearings and the inner faces of the wheel hubs, to retain lubricants. A wheeled trolley carrier constructed as described loperates asjfollowsi When traveling along a straight'piece of track thetwo wheels 4, 4, the sleeves 6 and the' shaft 3 all turn together and relative to the carrier 2 -andjthe housing or casing 7, the bearings.

The wheel 4', also rolling upon its track, turns upon the sleeve 6,. either faster than the wheel 4 ormore slowly, accordingly as the track which it'engages is the outer or inner one 'of the curve.. 'By this expedient the grinding or dragging of one wheel upon the track when the conveyer-pa'sses a curve is v avoided, the desired rolling action between the wheels and the rails being insured. It

will also be seen that the arrangement de- .scribed and illustrated will be apparent, however, tofthose familiar with the art that it is adapted for'use in connection with wheeled conveyers of manykinds and types, and therefore the invention is not limited to the specific showing thereof represented, nor beyond the terms of the accompanying claims.

What I claim is:

1. A vehicle comprising a shaft, a pair of wheels supported thereonfone secured fast thereto and the other free to turn thereon, antifriction bearings for the shaft, and a casing in which are located the bearings carried by the vehicle and located between the Wheels. l

2. A wheeled conveyer comprising a load carrier, a shaft supporting such carrier, traction Wheels on the shaft, one Wheelbeing keyed thereto and-the other free to turn relative thereto, and anti-friction'bearings between the load carrier and theshaft.

3. An overhead trolley conveyer comprising a depending load-carrier, a shaft supported in the upper portion of such carrier, traction .wheels on the shaft, one wheel being keyed thereto and the other free to turn thereon, a casing supported in the loadl carrier, and anti-friction" bearings for the shaft mounted in the said casing.

4. A trolley conveyor comprising a pair of traction wheels, av shaft on which such wheels-are supported, near its ends, a housing surrounding-the central portion of the shaft, two sets of antifriction bearings for the shaft supported in the said housing near its ends, a load carrier depending from the housing, and meansfor securing one of the wheels to the shaft so that'the two turn together, the opposite `wheel beingsupported on the .shaft so as to be free to turn thereon.

5. A vehicle lcomprising a shaft, a pair of Wheels supported at the ends of the shaft, one secured fast thereto and the other loose thereon, `a casing located between the wheels, antifriction bearings between the shaft and the casingy and a support for the loads to be carried by the Vehicle carried by the casing.

6. A vehicle .such as described in claim 5 wherein the load support is a hanger suspended from the casing in which are located the antifriction bearings.

7. A vehicle such as described 1n claim 5 including bushings supported on the ends lof the shaft, upon which are mounted the ran ed to take the outward en thrusts of theA earings. t BRINTON WELSER.
